To understand the book, it's essential to know its author. Alexander S. Langsdorf (1877-1973) was a distinguished engineer, author, and educator who played a pivotal role in shaping engineering education at Washington University in St. Louis. As a professor and dean for over 30 years, he was a tireless advocate for developing new curricula and graduate programs, a commitment that is deeply reflected in the meticulous nature of his writing. He left an indelible legacy at the university, which continues through the prestigious Langsdorf Scholars Program —a four-year, full-tuition fellowship named in his honor.
